This IC695RMX128 is a PACSystems RX3i redundant memory switching module manufactured by Emerson Automation (formerly GE Intelligent Platforms (GE IP)).

The module has 128MB of SDRAM user memory and supports operation as a reflective memory network or dedicated link between RX3i CPUs in a redundant configuration.

The module comes with single-mode fiber that supports 2.12 Gbaud fiber networks.

About the IC695RMX128

The IC695RMX128 is the PACSystems RX3i Redundant Memory Exchange Module.

The primary function of the module is to act as a single node on a reflective memory topology or as a dedicated memory module for redundant RX3i CPU pairs.

When used in a redundant CPU configuration, the IC695RMX128 reflects the contents of the IC695CMX128.

With a reflected memory link, any updates on one node are reflected and updated to all other nodes connected to the same network.

Connections are established over a fiber optic network supporting up to 256 nodes.

The module is equipped with 128 MB of reflective memory, and the fiber optic power supply requires an LC-type connector for transmission speeds up to 2.12 Gbaud.

The module operates on supplies of 580 mA @ 3.3 VDC and 220 MA @ 5 VDC.

The IC695RMX128 is intended for use in redundant systems and cannot be used to perform general purpose memory Xchange functions.

In addition, a full communication path must be established to complete the Memory Xchange network. The complete communication path consists of the primary RMX unit and the corresponding secondary RMX unit.

Two (2) high speed fiber optic cables must be connected www.cniacs.com to the RMX pair and must form a 2-node ring.

No other RMX or reflective nide may be used in any redundant controller design since a dedicated RMX module must be used for redundant controller configuration.

Configuration of the RMX nodes is done via programming software, not via jumper or DIP switch settings.
